The colour-matching functions of standard observers proposed by the CIE represent the normal colour vision for the worldwide population. But there are deviations in the colourmatching functions for real observers with a normal colour vision, so the observer metamerism index was defined by CIE to evaluate the mismatch between them in colour appearance. In this work, we present an alternative for...

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a ‎new method is introduced for determining the relationship between spectrophotometric ‎error and colorimetric inaccuracy. The error propagation in colorimetric parameter ‎calculation is evaluated using a linear relation between variance of reflectance spectra ‎and CIE tristimulus values. This linear formula ca...

This study focuses on the preventive effects of aqueous extract of Cichorium intybus (CIE) on streptozotocin (STZ) induced β-cell damage. Pancreatic β-cells or islet were treated with STZ in presence and absence of Cichorium intybus and the inhibitory effect of it against STZ toxicity were determined in RINm5F (RIN) rat insulinoma cells. Cell viability, Nitric oxide production and Insulin secre...

Many clinical laboratories are currently using counterimmunoelectrophoresis (CIE) as an aid in the rapid diagnosis of bacterial meningitis. Because cross-reactions among causative agents have been reported, the present study was undertaken to explore the problems that might occur when reference and commercial antisera are used in CIE. Broth cultures of 35 bacterial strains were tested with 76 r...

A counterimmunoelectrophoresis (CIE) technique which reacted positively with culture filtrates of Clostridium difficile was developed and compared with a cytotoxicity assay in human embryonic lung cell cultures. CIE, employing C. sordellii antitoxin, detected 17 of 17 C. difficile strains. Of those positive by CIE, 13 were cytotoxic in cell culture. Fourteen Clostridium species other than C. di...

The molecular mechanisms and the biological functions of clathrin independent endocytosis (CIE) remain largely elusive. Alix (ALG-2 interacting protein X), has been assigned roles in membrane deformation and fission both in endosomes and at the plasma membrane. Using Alix ko cells, we show for the first time that Alix regulates fluid phase endocytosis and internalization of cargoes entering cel...

The effect of gamma irradiation (0.5, 1, 2, and 4 kGy) on the quality of vacuum-packaged dry fermented sausages during refrigerated storage was evaluated. At Day 0 of irradiation, the pH, redness (CIE a), yellowness (CIE b), 2-thiobarbituric acid-reactive substances (TBARS) and volatile basic nitrogen (VBN) values of samples irradiated at 2 and 4 kGy were higher (po0.05), but the CIE L values (...

The CIE Board of Administration has proposed a new Division to study procedures and prepare guides and standards for the optical, visual and metrological aspects of the communication, processing, and reproduction of images, using all types of analogue and digital imaging devices, storage media and imaging media. While current practice enables adequate color communication within single industrie...

CIE colorimetry was standardised 65 years ago to describe colorimetric properties of signal lights. The first real application of CIE colorimetry occurred, however, in the textile and coating industries to describe colour matches between sample and reference. Thus also the experiments conducted to achieve a uniform colour scale diagram were performed by using material samples usually illuminate...
